To all whom it may concern:

Be it known that I, Annnn'r R. Smns, a citizen of the United States, residing at Potter Valley, in the county of Mendocino and State of California, have new and useful Improvements in a Vell- Drilling Machine, of. which the following is a specification.

The present. invention relates to improvements in well drilling machines, and more particularly to an under slung walking beam therefor. This improved walking beam is designed for use on well drilling machines for the reason that it will permit the spudding in, or starting of the well, without the use of a spudding attachment. The Well may be started without trouble and the operator may continue drilling Without changing to an overhead walking beam, as is-neoessary with an ordinary well drilling machine. With the use of this walking beam, the pull all comes from the rear of the machine, and from the center, thus making the machine more stable. The parts are of such a nature that there is very little liability of breakage. The structure is generally very simple, inexpensive to manuit'actitre,"

strong, durable, QfllClQlll) and reliable in operation, not likely to easily become out of order, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as 'will be hereinafter more fully described and claimed.

In the ,drawing:--

isjournaled in the upper end of invented certain end of a spring- 27 upper edge ot tbe end the standard 6. A prime mover 8 is mounted on the frame adjacent the standard 6 and drives a bull wheel 9 through the intermediary of a belt 10. A shaft ll is 'journaled on the frame 5, and mounts the bull wheel 9. A crank 12 is keyed to the shaft 11, as at 13, and is provided with a series of openlugs '14. A spudding or operating arm 15' is provided at its lower end with a laterally extending pintlc l6 receivable in the journal l7 on the lower edge of one end of a walk: lug beam 18. A pin 19 projects laterally from the upper end of the spudding arm 15 and is receivable in one of the openings 14 of the crank 12. journalcd at its center on a rod 20 carried intermediate the ends of the frame at the botlouredges thereof. is winch 22 is mounted on the frame, and a cable windable thereon is trained over a pulley 23 and under the pulley 24 carried by the resilient-inverted V-shaped bracket 25, and then over'the pulley' '7. The inverted l-shaped bracket 25 has one extremity fixed to the beam 18 as at 26 While the other extremity is fixed to one of the strap type, the other extremity of which is fixed'to a block 28 carried on the bottom. edge of the Walking beam. When the end of the walking beam 8 having the bracket 25 mounted thereon is moved downwardly, the cable; is

made taut and the bracket flexes until the spring 2'7 at its free end engages the walking beam. The flexing of the spring. 27 and the bracket 25 til-lords a cushioning eifect, tendmg to prevent snuliing of the cable when the machine is in operation.

A. bumper 2% is disposed transversely across the frame 5, and is engageable by the of the Walking beam adjacent thebracket 25. Rubber strips 30 may he provided on bumper bar 29. A clutch 32 is provided on the shaft 11 between the bull Wheel and said sheft'so that when the-clutch is released, said hull wheel. rotates free of the; shaft 11.

As the bull. Wheel shalt revolves the crank transmits rocking motion to the} Walking beam through the spuddingor driving arm.

The walking beam 18 is' the under surface of the l ion withdrawn from the well by operation of the winch. In starting the drilling, the drill is lowered to the proper depth by the winch, and the drilling is instantly started by simply engaging the clutch. As above stated no attachment is necessary to start or spud in a well, the machine is ready and no adjustment or changes necessary for the spudding in.

It is thought that the construction, operation, and advantages of the invention will be clearly understood without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention, and the above description. It will be apparent that numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages:

Having thus described the invention, what is claimed as new is 1. A well drilling machine including a frame, an underslung walking beam mounted on the frame, means associatedwith one'end of the walking beam for rocking the same, a resilient inverted V-shaped bracket having one end fixed adjacent the other end of the walking beam, aspring, a block fixed to the under edge of the walking beam adjacent the attachment of the arm of the bracket thereto, said spring having one end fixed to the block and the other end engageable with the. other end of the bracket, and a Wheel journaled in the apex of the bracket.

2. A well drilling machine including a frame, an underslug walking beam mounted on the frame, means associated with one end i of the Walking beam for rocking the same,

,a resilient inverted V-shaped bracket having one end fixedadjacent the other end of the walking beam, :1 spring, a block fixed to the under edge of the walking beam adjacent the attachment of the arm of the bracket thereto, said spring having one end fixed to the block and the other end engageable with i the other, end of the bracket, a Wheel jouralways nwaee'r naled in' the apex of the bracket, a winch on the frame, a pulley on the frame, an additional pulley mounted above the -frame at one end, and a cable trained over the last mentioned pulley, under the pulley on the bracket, and windable about the winch.

3, A well drilling machine otthe class described including a frame, an underslung walking beam pivotally mounted intermediate its ends to the frame at an intermediate portion thereof, a shaft journaled in the frame, a bull wheel loosely mounted on the shaft, means for driving the bull wheel, acrank attached to shaft, a clutchbetween the shaft and the bull wheel, a driv-v,

ing arm adiustably connected with the crank and pivota ly engaged with one end of the walking beam, abracket at the other end ofthe walking beam of a resilient inverted V-shaped formation having one end fixed to the beam a distance from the other end, a spring attached to the Walking beam adjacent said end of the bracket, and en ageable with the other end of the bracket, and a pulley in said bracket.

4:. A well drilling machine of the class described includin a frame, an underslung walking beam pivotally mounted intermediate its ends to the frame at an intermediate portion thereof, a shaft journaled in the frame, a bull wheel looselymounted on the shaft, means for driving the bull wheel, a crank mounted to the shaft, a clutch between the shaft and the bull wheel, a driving arm adjustably connected with the crank and pivotally'engaged with one tend of the walking beam, a resilient bracket at the other end of inverted Vshaped end fixed to the beam a distance from the other end, a spring attached. to the walking beam adjacent said end of the bracket, and engageable with the otherend of the bracket, a pulley in said bracket, a winch mounted on the frame, a pulley mounted on the frame, another pulley monntedjabove the frame, a cable trained the walking beam or an over the. last two-mentioned pulleys, under tbs-pulley in the about the winch.

In testimony whereof I aflix my signature.
